Graph the line with the equation
pochemuha

The graph of the linear equation can be seen in the image below.

<h3 /><h3>How to graph the linear equation?</h3>

Here we have the linear equation:

y = (2/5)*x - 6

To graph it, we just need to find two points on the line, and then connect them with a line.

To find the points we just evaluate in two values of x.

if x = 0.

y = (2/5)*0 - 6 = -6

Then we have the point (0, -6)

If x = 5.

y = (2/5)*5 - 6 = 2 - 6 = -4

Then we have the point (5, - 4)

Now we can graph these two points and connect them with a line. The graph of the line can be seen below.

The sum of three numbers is 69. The second number is 6 less than the first. The third number is 3 times the first. What are the
almond37 [142]

Answer and Step-by-step explanation:

To solve, we would set the first number to x, and make an equation.

<u>Solve for x.</u>

x + (x - 6) + 3x = 69.

<u>Add and combine like terms.</u>

2x + 3x - 6 = 69

5x - 6 = 69

<u>Add 6 to each side of the equation.</u>

5x = 75

Divide by 5 to both sides.

x = 15

<u>The first number is 15.</u>

<u>The second number is (x - 6) = (15 - 6) = 9.</u>

<u>The third number is 3x = 3(15) = 45.</u>
